KNOTTING APPARATUS FOR GRAIN-BINDERS.

SPECIFICATION forming part of Letters Patent No. 352,602, dated November16, 1886.

Application filed April 21, 1886. Serial No. 199,602.

To all whom it may concern:

Be it known that I, J OHN F. APPLEBY, of Minneapolis, Minnesota, haveinvented a certain Improvement in Knott-ing Apparatus for Grain-Binders,of which the following is a specification.

This improvement relates to the type of knotting apparatus in which therotating knottershaft is journaled in a swinging frame; and theinvention embraces three special features: First, the combination, withsuch a swinging frame, of the swinging tucker-arm carrying the pawl forimpelling the cord-holder disk, and means for rocking the swingingknotter-shaft frame and the tucker and pawl-carrying arm, respectively,toward and from each other at appropriate stages of the knottingoperation; secondly, the provision of a cord-guiding hook which isaffixed to and moves with the swinging knotter-shaft frame on the sidethereof toward the cord-holder, and which, during the operation offorming the loop upon the knotting-bill, serves to hold the cordextending from the knotting-bill to the cord-holder away from a fixedknife, which is between the hook and the cord'holder, and which, afterthe formation of the knot, pulls the binding-cord against the knife, andthus assists in severing it.

The third feature of the invention consists in mounting upon a commonpivot the swinging knotter shaft frame and the swinging tucker carryingthe pawl for impelling the cord-holder disk.

The accompanying drawings of knotting apparatus embodying theimprovements are as follows:

Figure l is a vertical section through the offset dotted line x x onFig. '2, affording a view in elevation of the knotter-operating wheel.Fig. 2 is an elevation, partly in section, of the knotting apparatus.Fig. 3 is a vertical section throughthe offset dotted line, affording aview in elevation of the grooved face of the cam for operating thetucker, and the pawl for impelling the disk of the cord-gripper. Figs. 4and 5 are elevations of thestubble side of the knotting apparatus, ineach of which a portion of the bracket which supports the shield isrepresented asbroken away, and which re- (No model.)

spectively show the swinging frame in which the knotter-shaft is mountedand the tuckerarm in two different positions. Fig. 6 is an elevation ofthe stubble side of the apparatus, representing the parts in thepositionsv in which they are represented in Fig. 51 Fig. 7 is ahorizontal section through the dotted line y y on Fig. 5.

In the knotting apparatus represented in the drawings the knotteroperating wheel A is provided with the segmental gear A, for engagingthe knotter-shaft pinion B, and thereby rotating the knotter-bill toform the loop. The knotter-shaft is mounted in the swinging frame 0,which is provided at its upper end, upon the side toward theknotter-operating wheel A, with a laterally-projecting stud carrying theanti-friction roller 0. The camgroove to in the face of theknotter-operating wheel A, by engaging the roller 0'', imparts therequired toand-fro swinging movement to the frame 0. 0n the sideopposite to that carrying the roller 0 the frame 0, at its upper end, isprovided with the laterally-projecting ears 0 and G which are perforatedto receive the pivot D, upon which the frame 0 rocks. The pivot D isinserted through appropriate perforations in the standards E E, whichare cast in one'piece with the sleeve E, through which the khotter-wheel shaft A extends. The lower ends of the standards E E arebolted to the shieldplate 6, provided with the usual slot, e,'throughwhich the cord-arm Works.

The knotter-bill consists of the usual hook, I), and the pivoted jaw b,which, during the operation of forming the loop, is held down againstthe hook I) in the usual manner bythe end with the perforatedhub G, bymeans of which it is hung on the pivot D. A short arm projectinglaterally from the upper end of the tucker-arm G carries theanti-friction roller G, which is engaged by the cam-groove g in the faceof the cam-wheel g, affixed to the prime shaft A.

By means of the cam-grooves a and y engaging, respectively, the rollersO and G the knotter-shaft frame 0 and the tucker-arm G- are rockedtoward and from each other at appropriate stages of the knottingoperation.

The pawl h, for impelling the'cord-holder disk H, is pivoted to the sideof the tuckerarm G, and the cam-grooveg thus performs the additionalfunction of giving the necessary motion for operating thecord-holderdisk H.

What is claimedjas the invention is- 1. In knotting apparatus for grainbinders, the combination, as herein set forth, of a cord-holder, aswinging tucker-arm carrying the pawl for impelling the cord-holderdisk,a

swinging frame carrying the rotating knottershaft, and means for rockingthe tucker and pawl-carrying arm and theknotter-shaft frame toward andfrom each other at appropriate stages of the knotting operation.

'2. The knotter-sh'aft frame 0, the tucker and pawl-carrying arm G, thepivot D, serving as a common axis for the frame 0, and the arm G, acord-holder,and means for imparting swinging movements toward and fromeach other to the frame 0, and the tucker and pawl-carrying arm G atappropriate stages of the knotting operation.

3. The cord-guiding hook F, mounted upon the swinging frame (1, incombination with the knotting'bill and cord-holder, and the stationaryknife F, asand for the purposesset forth.
